About this Gig

Need a smart contract or a complete DApp built by someone who understands both blockchain and full-stack development? That is exactly what I do.


What I deliver:

  • Solidity smart contracts: tokens (ERC-20, ERC-721, ERC-1155), staking, vesting, marketplaces and custom logic
  • - Full DApps: web3 frontend with wallet connect plus backend and APIs
  • - Thorough unit tests (Hardhat or Foundry) and gas optimization
  • - Deployment to Ethereum, Polygon, BSC, Arbitrum, Base or any EVM chain
  • - Clean, documented source code you fully own

Why me:

  • Full-stack background means your DApp is polished end to end, not just the contract
  • - Security-minded coding with audit-ready test coverage
  • - Clear communication and on-time delivery

Note: I provide technical development services only, no financial or investment advice.


Message me with your project idea and I will scope it and give you an exact quote before you order.
